I have been trying it out in the past few days and it looks really good. Brings together the features I use from Notepad++ and Sublime.
I have installed multiple packages like json formatting, lint, xml formatting, sublime style columns, script, minimap and it works really well. I like having the find/replace at the bottom of the UI (like in Sublime). Had one issue with Regex though it might be user error.
Dark themes are easy to set up. No complaints so far. I will play a bit more with remote editing, and other packages to make the final call.
